Perforated Metal

Request for quotation

Perforated Metal, also known as perforated sheet, perforated plate, or perforated screen, is a sheet metal that has been manually or mechanically stamped or punched to create a pattern of holes, slots, or decorative shapes.

Perforated materials are used in a number of different applications for a variety of reasons. Used as screens, filters, shields, and guards, perforated materials can control the passage of air, liquid, light, solids, heat, electromagnetic waves, and sound waves. In addition, perforated materials are also used for aesthetics in architectural and design applications such as facades, fixtures, and privacy panels.

We fabricate perforated sheets in round holes, slotted holes, square holes, rectangular holes, hexagonal holes and ornamental holes. The holes may be in straight or staggered patterns.

The materials that we offer for perforation include Stainless Steel, Aluminum, B.I., Galvanized, Copper, Brass and Aluminum Composite Panel (ACP).

We also offer special-size and special-pattern perforation, together with picture perforation.
